AGENT ited rates This invention relates to sheet metal awnings ofimproved design as hereinafter particularly pointed out.

Among the objects of the invention are to provide a novel and improvedsheet metal awning. It is a par ticular object of the invention toprovide an awning which can be easily fabricated and easily erected. Afurther object of the invention is to provide an awning which iseconomical in construction and which can be assembled very quickly. Itis also an object to minimize the proportion of scrap in the manufactureof sheet metal awnings. Other and further objects of the invention willbe apparent as the detailed description of the invention proceeds.

In the drawings Fig. l is a perspective view of one form of the awningattached to an ordinary window.

Fig. 2 is an enlarged view of a section of Fig. 3 at the junction of theinclined portion and the skirt portion of the awning panels.

Fig. 3 is a cross sectional view of the awning.

Fig. 4 is a cross sectional view of the roof and drain panels.

Fig. 5 is an enlarged perspective view showing a portion of oneembodiment of the front rail of the frame.

Fig. 6 is a cross sectional view of a drain panel show ing one means ofsecuring it to the front rail.

In the embodiment of the invention shown in the drawings a simple roofform applicable to an ordinary window is shown for purposes ofillustration. However, the form and design may vary depending upon thetype of building and the part to which the awning is attached. Thepreferred material of construction is aluminum but steel, magnesium andother sheet metal materials may be used.

The awning includes a simple horizontal frame comprising a front memberor rail 2 and side members at right angles thereto. A side member 1 isshown in Fig. 3. The end next to the building is provided with a meansfor securing it thereto, as for example by means of a clip 3. Above theplane of the frame next to the building is a horizontal rail 4. Thisserves as a support for the panels of the roof and for securing theawning to the building or like support by means of wood screws 15, boltsor the like.

Supported by the parallel, horizontal rails 2 and 4 are a series ofalternate drain and roof panels 7 and 7a. These include verticallydisposed extensions which provide a skirt at the front of the awning.The drain panels 7 are provided at the edges thereof with upturned,crimped flanges 9 at right angles to the plane of the surface. The roofpanels are provided with downturned, crimped flanges 9a at right anglesto the plane of the surface. From the standpoint of manufacture the roofand drain panels actually are identical except in the direction of thebend forming the skirt but differ in their relative positions. This ofcourse provides great economy in manufacture and a saving of metal. Thedrain panels are secured to the upper rail by metal screws 6 visibleatent F 2,788,548 Patented Apr. 16, 1957 in Figs. 1 and 3. Metal screws6 visible in Figs. 2 and 6 are also employed to secure the drain panelsto the lower rail.

As shown in Fig. 4, the roof panels are held in place very simply by thecrimped flanges. In erecting the awning the drain panels are firstcorrectly spaced and secured. Then the roof panels 7a are snapped inplace. The latter overlap the drain panels, providing a water tightconstruction. The crimped flanges are in close juxtaposition so thatboth lateral and vertical movement is prohibited. This arrangementobviates the necessity of using screws or clips for fastening the roofpanels.

Whether the awning is prefabricated or assembled on the building, theassembly can be done very quickly and easily.

As illustrated in Fig. 5, studs 12 are provided on the front rail bycutting out and upturning portions of the metal at the spacings requiredby the widths of the panels. The flanges of the drain panels are securedto these studs by means of metal screws 6 visible in Fig. 6. The screwsare then hidden by the flanges of the overlapping roof panels 7a. It isalso feasible to secure the drain panels to the front rail by screwsthrough the flat surface of the panels instead of screws through theflanges and studs. In this embodiment of the invention (not shown) theheads of the screws through the drain panels and front rail would bevisible from the front of the awning. In such case it is preferred tosecure the drain panels to the front rail at the vertical skirt portioninstead of at the inclined portion. This provides a durableconstruction. The skirt is normally within easy reach of passersby sothat if unsupported it is liable to be bent or mutilated, spoiling theappearance of the awning.

In the embodiment of the invention illustrated the front rail serves asa brace for the skirt although the hidden screws are in the flanges atthe inclined portion of the drain panels. It will be apparent that ifdesired the studs 12 could be so positioned in the front rail that thehidden screws could be in the skirt portion.

The sides of the awning are provided with a curtain comprisingvertically disposed parallel panels 8. These are provided at the edgeswith flanges 10 turned outward at right angles to the plane of the panelsurface. Of course these flanges need not be crimped and preferably areplain as illustrated. The panels of the curtain are spaced apart toallow free air circulation underneath the awning as shown in Fig. 3. Themetal screws 6 fasten the bottom of the panels to the side section ofthe frame 1. At the top they are secured to an inclined bracing member5. This bracing member is also secured to a flange of the panel at theedge of the inclined roof and drain sections.

In the embodiment illustrated in Fig. l, the edge of the awningterminates in a drain panel 11 which has on one side an upturned crimpedflange as herein described interlocked with the overlapping roof panel.At the edge of the awning, however, it has a downturned plain flange 16.Metal screws pass through this flange, the curtain panels and theinclined bracing member. The width of the panels at the edges may varyfrom the others to permit adjustment to the exact width of awningdesired.

Since the flanges of the alternate roof and drain panels are crimped, itis not convenient to overlap them at the bend for the skirt so awing-shaped section of the metal, not shown, is cut from the panels atthe point desired for the bend. Referring to Fig. 2, the bending of thedrain panels results in a widening of the notch so that in the assembledawning there appears a wide notch 13 in the drain panel. The bending ofthe roof panels is of course in the other direction with respect to thenotch so that the edges of the metal almost meet, leaving the small gap14.

It is apparent from the foregoing that a very simple economical sheetmetal awningis provided. Equivalentswill berobvious to those skilled inthe art. For example instead of metal screws, rivets and other means maybe used: to fasten the drain panels to the rails. The dimensionsof thepanels and flanges may vary as desired. It has been found that a /3 in.overall width of the roof and. drain panels is convenient and attractivein appearance and canbe conveniently made up from 7 in. strip aluminum.The. distance from the surface of the panel to the beginning; of thecrimp is conveniently about in. and, from, this point to the end of theflange about in. Atcrimp about in, depth measuring at the deepestportion from the plane of the surface of the flange to the insidesurfaceof the metal at thev bottom of the crimp is very satisfactory for securelocking.

It is intended to cover all changes and modifications of the examples ofthe invention herein chosen for purposes ofdisclosure which do notconstitute departures from the spirit and scope of the invention.
